Description

  The present invention relates to a notification system.

  2. Description of the Related Art Conventionally, there has been known a technique of acquiring biological information from a patient in a hospital bed and outputting an alarm sound because there is a risk to the patient's living body when a measured value of the biological information deviates from a set range. . The alarm sound is output to call a staff (a nurse, an assistant staff, or the like) from a nurse station or the like.

  However, there are cases where the measured value of the acquired biological information sharply increases (or sharply decreases) due to factors such as noise. In this case, the measured value deviates from the set range, and an unnecessary alarm sound is output.

  Therefore, in the technology described in Patent Document 1, the amount of time (continuous time) in which the measured value of the biological parameter (biological information) deviates from a predetermined range (set range) so that an unnecessary alarm sound is not output. When the signal exceeds a predetermined level (set time), an alarm sound is output.

Japanese Patent No. 4553337

  As described above, when there is a risk to the living body of the patient, an alarm sound is output from a nurse station or the like to call a staff (a nurse or an assistant staff). In this case, when the staff goes near the patient, the staff gives an instruction (operation) to stop the output of the alarm sound, and responds to the patient.

  However, in the technique described in Patent Document 1, an alarm sound is output each time a continuous time during which a measured value of biological information deviates from a set range exceeds a set time. In this case, since the alarm sound is troublesome when the staff is dealing with the patient, it is necessary to give an instruction (operation) to stop the output of the alarm sound. This is because the above operation must be performed every time an alarm sound is output, even though the staff is handling a patient, and the above operation is troublesome as well as the alarm sound.

  However, even if the alarm sound is bothersome, if the staff is responding to the patient and the measured value is out of the set range, the risk to the patient's living body has not been solved yet. It is a fact.

  In view of the above-described problems, an object of the present invention is to provide a notification for calling a staff member when there is a risk to a patient's living body, and to notify the patient when the staff member is handling the patient. It is an object of the present invention to provide a notification system that allows a staff member to recognize that a risk to a living body has not yet been resolved, and a notification system that can perform the notification.

  The notification system according to the present invention is a notification system that monitors and notifies the first condition in which the state of the care recipient is set in the alarm monitoring state, wherein the state of the care receiver deviates from the first condition. An alarm is output in the alarm notification state, and a first notification unit mounted on the first device displays first information when the alarm is output, and a second notification different from the first device. A second notification unit mounted on the device, wherein in the alarm notification state in which the alarm and the first information are output, when a caregiver instructs the first device to stop an alarm, the first notification is performed. The notifying unit stops outputting the alarm, and the second notifying unit keeps displaying the first information.

  According to the present invention, a notification (alarm, first alarm display information) for calling the staff when there is a risk to the patient's living body, and a notification to the patient's living body when the staff is handling the patient. (First alarm display information) for causing the staff to recognize that the risk has not been solved yet.

A program 136 and a biological information display program 138 are stored. Here, the alarm threshold table 122 and the program are stored in the storage unit 110 of the display terminal 1000 in FIG. 3, but may be stored in a storage unit described later of the connection device 2000.

  In the individual electronic medical record data 120, an electronic medical record of a patient is stored as data. A collection of information representing the individual medical record as individual electronic medical record data 120 is stored in the electronic medical record server 40 (FIG. 1). In the present embodiment, the description will be made assuming that the data is stored in the storage unit 110, but the data of the electronic medical record server 40 (FIG. 1) may be directly used. In this case, the individual electronic medical record data 120 need not be stored in the storage unit 110.

  The alarm threshold table 122 stores alarm thresholds as thresholds of various measurement values. When the measured (received) measured value deviates from a predetermined range (when the measured value exceeds the upper alarm threshold value or when the measured value is less than the lower alarm threshold value), notification is performed. And error handling. This alarm threshold may be set in advance or may be set arbitrarily.

  The storage unit 210 is a functional unit that stores various programs necessary for the operation of the connection device 2000 and various data. The storage unit 210 is configured by, for example, a semiconductor memory, an HDD, or the like.

  The NFC communication unit 220 is a functional unit for performing NFC communication with another device or an authentication card. When the authentication card 65 (FIGS. 1 and 2) is held over, the authentication process is executed. When the measurement device 60 (FIGS. 1 and 2) has an NFC communication function, the biological information can be received via the connection device 2000 by holding the measurement device 60 over the measurement device 60. The measuring device 60 may be, for example, a communication device such as a smartphone.

  The interface unit 230 is a functional unit for communicating with another device. For example, it is provided as a functional unit for connecting to the state detection device 20.

The light notification unit 264 is normally invisible, and may be configured to display by lighting or blinking only when notifying.

[3. Screen (state) transition diagram]
FIG. 6 is a screen transition diagram (state transition diagram) showing a screen displayed on the display unit 170 of the display terminal 1000 in FIG.

  First, when the system is started, it is determined whether or not an alarm is occurring, that is, whether or not each measured value exceeds an alarm threshold (or whether or not each measurement value is below an alarm threshold). Then, an alarm screen (P100) is displayed as needed. On this alarm screen, you can confirm that a problem has occurred, but the details of the error will not be displayed until you log in. As a result, it is possible to prevent the error contents that should not be displayed to the patient P (FIG. 1) or the family from being displayed.

  Note that the alarm screen is also displayed at the time of system startup such as when the power is turned on, but it may be determined at any time whether or not an alarm is occurring. When an alarm occurrence situation occurs, a transition to an alarm screen may be made as an interrupt process.

  Subsequently, a patient state display screen (P102) is displayed as a main state. On this screen, name plate information, pictogram information, alert information, an error state, and the like of the patient P (FIG. 1) are displayed. As a result, necessary information can be displayed for a medical worker such as a nurse or a doctor, an assistant, or a family member who assists.

  The patient status display screen (P102) does not display detailed information because a patient P (FIG. 1), a family member at a hospital, and a third party who has visited can be seen. If necessary, an authentication process is executed and login is performed to switch to a login screen (P104). It is possible to transition from the login screen to various screens. For example, a biological information display screen (P106) for displaying biological information (each measured value), a graph display screen (P108) for displaying a transition of the measured value, and a vital registration for registering the measured value in the electronic medical record. It is possible to switch to the screen (P110).

  It is also possible to switch to an alarm setting / history screen (P116) for setting conditions for an alarm occurrence situation. On the alarm setting / history screen, not only the setting of the alarm threshold value, but also other alert information and operations to be performed next (for example, instructions for medication) can be operated.

  As described above, according to the patient status display system 1 (FIG. 1), information on the patient P (FIG. 1) can be displayed in a unified manner, and by switching screens as necessary, appropriate information can be displayed. It can be displayed. In addition, information about the patient P (FIG. 1) can be centrally managed by centrally acquiring information on a plurality of measuring devices and registering the information in the electronic medical record.

[4. Processing flow]
Next, the flow of processing in the display terminal 1000 (FIG. 3) of the patient state display device 10 (FIGS. 1 and 2) of the patient state display system 1 (FIG. 1) will be described.

[4.1 Main processing]
FIG. 7 is a flowchart showing the operation (main processing) of the display terminal 1000 in FIG. The main process is a process realized by the control unit 100 of the display terminal 1000 of FIG. 3 reading out and executing the main program 132 stored in the storage unit 110.

  First, it is determined whether or not an alarm has occurred (step S102). Specifically, it is determined whether or not the various measured values deviate from a predetermined range (whether or not the various measured values exceed an upper alarm threshold, and whether or not the various measured values are less than a lower alarm threshold). Is done. When the various measured values deviate from the predetermined range (when the various measured values exceed the upper alarm threshold or when the various measured values are less than the lower alarm threshold), an alarm is generated and an alarm sound is issued. There is a need. If it is necessary to make an alarm sound, an alarm process is executed (Step S102; Yes → Step S104). Here, in the alarm processing, an alarm screen may be displayed on the display unit 170 (FIG. 3) as an interruption processing.

  It should be noted that whether the various measured values deviate from a predetermined range (whether the various measured values exceed the upper alarm threshold, and whether the various measured values are less than the lower alarm threshold) is determined based on the biological information. Depends on the type. Further, when the criterion is not a predetermined range but is determined based on only one alarm threshold (that is, when it is determined whether only the measured value exceeds the upper alarm threshold, or when the measured value is less than the lower alarm threshold). May be determined only).

  Subsequently, a patient state display process is executed (step S106). In the patient state display process, a patient state display screen (P102) (FIG. 6) is displayed on the display unit 170 (FIG. 3). Here, if the login authentication is not performed (or if the login fails), the processing is repeatedly executed from step S102 (step S108; No → step S102).

  If the login authentication has been correctly performed (Step S108; Yes), the login screen (P104) (FIG. 6) is displayed on the display unit 170 (FIG. 3) (Step S110). That is, the screen displayed on the display unit 170 (FIG. 3) switches from the patient state display screen (P102) to the login screen (P104). The login screen (P104) is a screen on which the staff can select various processes.

  Here, when "display biological information" is selected as the staff processing, biological information display processing is executed (step S112; biological information display → step S116). In the biological information display process, a biological information display screen (P106) (FIG. 6) is displayed on the display unit 170 (FIG. 3).

  When “setting” is selected, a setting process is executed (step S112; setting → step S118). In the setting process, an alarm setting / history screen (P116) (FIG. 6) is displayed on the display unit 170 (FIG. 3). The setting process includes setting an alarm threshold and registering / updating patient information.

  Here, if the logout is not executed, the login state continues (Step S114; No → Step S110). If the logout is executed, the logout is performed, and the processing is repeatedly executed from Step S102 (Step S114; No → Step). S102).

[4.2 Setting process]
In the setting process, the condition from the alarm monitoring state (described later) to the alarm notification state (described later), the notification method, and the condition to the alarm monitoring state are determined according to the type of the biological information 112, the type of measurement, and the item. Is set. FIG. 8 is a diagram for explaining the setting process of FIG.

  First, a case where the biological information 112 is the continuous biological information 114, the measurement is “measurement”, and the item is “respiration” will be described. The condition from the alarm monitoring state (for example, see step S202 in FIGS. 9 and 10) to the alarm notification state (for example, see step S206 in FIGS. 9 and 10) is defined as a continuous time during which the measured value is out of the set range. (For example, the continuous time in which the measured value exceeds the upper alarm threshold, and the continuous time in which the measured value is less than the lower alarm threshold) (for example, see the continuous time T1 in FIG. 10) is the first set time (for example, FIG. 10). This is the case when the alarm time is equal to or longer than the first set time Tth1. As the notification method at this time, an alarm sound output (for example, see the alarm sound AL in FIG. 10) and a warning display process (for example, the warning display in FIG. 10) Information W1 (blinking) and warning display information W2 (lit) are executed. In addition, the condition for the alarm monitoring state is that, after the completion of the alarm response, the continuous time when each measured value is within the set range (the continuous time when the measured value is equal to or less than the upper alarm threshold, and the continuous time when the measured value exceeds the lower alarm threshold) The time (for example, see the continuous time T2 in FIG. 10) is longer than the second set time (for example, see the second set time Tth2 in FIG. 10).

  Next, a case where the biological information 112 is the continuous biological information 114, the measurement is “measurement”, and the item is “pulse” will be described. The condition from the alarm monitoring state (for example, see step S202 in FIGS. 9 and 10) to the alarm notification state (for example, see step S206 in FIGS. 9 and 10) is defined as a continuous time during which the measured value is out of the set range. (For example, the continuous time in which the measured value exceeds the upper alarm threshold, and the continuous time in which the measured value is less than the lower alarm threshold) (for example, see the continuous time T1 in FIG. 10) is the first set time (for example, FIG. 10). This is the case when the alarm time is equal to or longer than the first set time Tth1. As the notification method at this time, an alarm sound output (for example, see the alarm sound AL in FIG. 10) and a warning display process (for example, the warning display in FIG. 10) Information W1 (blinking) and warning display information W2 (lit) are executed. In addition, the condition for the alarm monitoring state is that, after the completion of the alarm response, the continuous time when each measured value is within the set range (the continuous time when the measured value is equal to or less than the upper alarm threshold, and the continuous time when the measured value exceeds the lower alarm threshold) The time (for example, see the continuous time T2 in FIG. 10) is longer than the second set time (for example, see the second set time Tth2 in FIG. 10). Here, the setting range (upper alarm threshold, lower alarm threshold), the first set time, the second set time, and the like are different from the case of “breathing”.

  Next, a case will be described in which the biological information 112 is the continuous biological information 114, the measurement is “bed determination” based on the determination of the bed 3 (FIG. 1), and the item is “leaving from bed”. The condition from the alarm monitoring state to the alarm notification state is when the bed 3 (FIG. 1) is determined to leave the bed in the alarm setting state of leaving the bed. As a notification method at this time, an alarm sound output, a warning display process (for example, Warning display information (flashing)) is executed. Further, the condition for the alarm monitoring state is when the bed 3 (FIG. 1) determines that the bed 3 (FIG. 1) is in bed from the determination of leaving the bed.

  Next, the case where the biological information 112 is the continuous biological information 114, the measurement is “bed determination” based on the determination of the bed 3 (FIG. 1), and the item is “end sitting” will be described. The condition from the alarm monitoring state to the alarm notification state is when the bed 3 (FIG. 1) determines the end sitting position in the alarm setting state of the end sitting position. As a notification method at this time, an alarm sound output, a warning display process ( For example, warning display information (flashing) is executed. The condition for the alarm monitoring state is a case where the bed 3 (FIG. 1) determines that the bed 3 (FIG. 1) is in bed from the end sitting position determination.

  Next, a case will be described in which the biological information 112 is the continuous biological information 114, the measurement is “bed determination” based on the determination of the bed 3 (FIG. 1), and the item is “get up”. The condition from the alarm monitoring state to the alarm notification state is when the bed 3 (FIG. 1) is determined to be up in the rising alarm setting state. As a notification method at this time, an alarm sound output, a warning display process (for example, Warning display information (flashing)) is executed. The condition for the alarm monitoring state is a case where the bed 3 (FIG. 1) is determined to be lying up from the determination of rising.

  Next, the biological information 112 is the measured biological information 116, the measurement is “measurement”, and the items are “blood pressure”, “SpO2 (percutaneous arterial oxygen saturation)”, “blood sugar”, and “body temperature”. The case will be described. The condition from the alarm monitoring state to the alarm notification state is that when the staff measures the patient P (FIG. 1) during the round, various measured values deviate from the set range. A warning display process is performed. At this time, since the staff stops executing the warning display process, the condition for the alarm monitoring state is not set.

  FIG. 9 is a diagram for explaining a state set in the setting process, and is a flowchart showing the alarm process of FIG. As shown in FIG. 9, in the setting process, as a procedure for executing the alarm process, when an alarm condition occurs during “alarm monitoring”, the process proceeds to “alarm occurring” and the alarm condition is released. To "monitoring alarm". If the staff gives an instruction to stop alarm monitoring during “alarm monitoring”, “alarm monitoring is stopped”. In “monitoring alarm”, an alarm monitoring state described later (step S202) is set. In the “alarm occurring”, an alarm notification state (step S206), an alarm response state (step S208), and an alarm observation state (step S212) described later are set. In the “alarm monitoring stop”, the staff does not issue an alarm monitoring stop instruction, and thus does not enter the alarm monitoring state (step S202) described later.

[4.3 Alarm processing]
The alarm process needs to be performed based on the measured value (measured value) even when the staff is not near the patient P (FIG. 1). Therefore, FIG. 9 shows the case where the biological information 112 (FIG. 8) is the continuous biological information 114 (FIG. 8), the measurement is “measurement”, and the item is “respiration” or “pulse”. It will be described using FIG. The alarm process is a process executed in step S104 of FIG. 7, and is a process realized by the control unit 100 of the display terminal 1000 of FIG. 3 reading and executing the alarm program 134 stored in the storage unit 110. It is.

  First, in the alarm monitoring state (step S202), the control unit 100 (FIG. 3) determines whether the measured value of “breathing” or “pulse” is out of the set range (the measured value exceeds the upper limit alarm threshold). Whether the measured value is less than the lower alarm threshold).

  Now, in the alarm monitoring state (step S202), the measured value of “breathing” or “pulse” does not deviate from the set range (the measured value does not exceed the upper alarm threshold, or the measured value is less than the lower alarm threshold). is not). In this case, since no alarm situation has occurred (No at Step S204), the control unit 100 (FIG. 3) executes Step S202.

  Now, in the alarm monitoring state (step S202), the measured value of “breathing” or “pulse” is out of the set range (the measured value exceeds the upper alarm threshold, or the measured value is less than the lower alarm threshold). Is). In this case, the control unit 100 (FIG. 3) needs to monitor whether an alarm situation occurs. Therefore, if the continuous time during which the measured value of “breathing” or “pulse” deviates from the set range is equal to or longer than the first set time, an alarm condition has occurred (step S204-Yes). Shifts from the alarm monitoring state (step S202) to the alarm notification state (step S206).

  In the alarm notification state (step S206), the control unit 100 in FIG. 3 controls the sound notification unit 262 of the notification unit 260 of the connection device 2000 to output an alarm sound, and outputs first alarm display information. In this way, the light notification unit 264 of the notification unit 260 of the connection device 2000 is controlled. Here, the sound notification unit 262 of FIG. When the alarm program 134 shown in FIG. 3 exists in the connection device 2000, the control unit 200 may control the sound notification unit 262.

  In the alarm notification state (step S206), when the staff instructs the display terminal 1000 (or the connection device 2000) of the patient state display device 10 of FIG. 2 to stop the alarm, the control unit 100 (FIG. 3) Then, the sound notification unit 262 (FIG. 3) is controlled to stop outputting the alarm sound. The alarm processing shifts from the alarm notification state (step S206) to the alarm response state (step S208). Here, in the alarm notification state (step S206), the alarm notification is also notified to the terminal device 50 (FIG. 1) and the portable terminal device 55 (FIG. 1), and an alarm sound is issued to the terminal device 50 and the portable terminal device 55. Generate a vibe. Even when the terminal device 50 or the portable terminal device 55 instructs to stop the alarm, the control unit 100 may control the sound notification unit 262 to stop the output of the alarm sound.

  In the alarm response state (step S208), the staff responds to the patient P (FIG. 1). In this case, the light notification unit 264 (FIG. 3) continues to output the first alarm display information.

  In the alarm response state (step S208), the staff responds to the patient P (FIG. 1) and operates the display terminal 1000 (or the connection device 2000) of the patient status display device 10 in FIG. If so, the alarm response state (step S208) is completed. That is, the alarm response is completed. If the measured value that has deviated from the set range has fallen within the set range after the alarm response completion operation (if the measured value that exceeded the upper limit alarm threshold does not exceed the upper limit alarm threshold, or If the measured value is not less than the lower alarm threshold), the alarm situation is resolved (step S210-Yes). In this case, the alarm processing shifts from the alarm response state (step S208) to the alarm monitoring state (step S202).

  On the other hand, in the alarm response state (step S208), the staff responds to the patient P (FIG. 1) and completes the alarm response to the display terminal 1000 (or the connection device 2000) of the patient state display device 10 in FIG. The operation has been performed, but the measured value of "breathing" or "pulse" is still out of the setting range (the measured value is higher than the upper alarm threshold or the measured value is lower than the lower alarm threshold) . In this case, since the alarm condition has not been resolved (No at Step S210), the control unit 100 (FIG. 3) needs to observe whether the alarm condition occurs again. Therefore, the alarm processing shifts to the alarm observation state after the operation of completing the alarm response in the alarm response state (step S208) (step S212).

  In the alarm observation state (step S212), when the measured value that has deviated from the set range has fallen within the set range (when the measured value that has exceeded the upper limit alarm threshold has not exceeded the upper limit alarm threshold, or the lower limit alarm has been set). If the measured value that was less than the threshold is not less than the lower alarm threshold), the control unit 100 (FIG. 3) needs to further monitor whether an alarm condition occurs. Therefore, the control unit 100 (FIG. 3) controls the light notification unit 264 (FIG. 3) so as to output second alarm display information different from the first alarm display information.

  Now, in the alarm observation state (step S212), if the continuous time during which the measured value of “breathing” or “pulse” does not deviate from the set range is equal to or longer than the second set time, no alarm condition has occurred. (Step S214-Yes), the control unit 100 (FIG. 3) controls the light notification unit 264 (FIG. 3) so as to stop outputting the second alarm display information. The alarm processing shifts from the alarm observation state (step S212) to the alarm monitoring state (step S202).

  On the other hand, in the alarm observation state (step S212), if the continuous time during which the measured value of “breathing” or “pulse” does not deviate from the set range is less than the second set time, the alarm situation may occur again. (Step S214-No).

  Here, when the time after the alarm response completion operation has not passed the third set time longer than the second set time, that is, when the time is not over (step S216-No), the control unit 100 ( FIG. 3) executes step S212.

  Alternatively, even if the time after the alarm response completion operation has passed the third set time, the alarm processing has not transitioned from the alarm observation state (step S212) to the alarm monitoring state (step S202), ie, If the time is over (step S216-Yes), the alarm processing shifts from the alarm observation state (step S212) to the alarm notification state (step S206).

[5. Operation example]
Subsequently, an example of the operation of the present embodiment will be described. FIG. 10 is a timing chart for explaining an example of the alarm process of FIG.

  First, whether the measured value V of “breathing” or “pulse” deviates from the set range Rth (whether the measured value V exceeds the upper limit alarm threshold Vth1 or whether the measured value V is less than the lower limit alarm threshold Vth2) Is monitored (step S202: alarm monitoring state).

  Now, at time t1, the measured value V of “breathing” or “pulse” is out of the setting range Rth. For example, the measured value V exceeds the upper alarm threshold Vth1. Further, at time t2 after time t1, the continuous time T1 during which the measured value V of “breathing” or “pulse” deviates from the set range Rth is equal to or longer than the first set time Tth1 as the above-described first set time. (T1 ≧ Tth1), an alarm situation has occurred (Step S204-Yes).

  At time t2, the sound notification unit 262 outputs the alarm sound AL. The light notification unit 264 outputs the first alarm display information W1. For example, the light notification unit 264 is a light emitting element such as an LED (Light Emitting Diode), and the LED is blinked and displayed as the first alarm display information W1 (step S206: alarm notification state).

  When the staff instructs to stop the alarm at time t3 after time t2, the sound notification unit 262 stops outputting the alarm sound. In this case, the light notification unit 264 continues to output the first alarm display information W1. That is, the light notification unit 264 is blinking. At this time, the staff responds to the patient P (FIG. 1) (step S208: alarm response state).

  At time t4 after time t3, the staff corresponds to patient P (FIG. 1). Here, the staff responds to the patient P (FIG. 1) and performs an operation for completing the alarm response on the display terminal 1000 (or the connection device 2000) of the patient status display device 10 in FIG. In this case, the light notification unit 264 outputs second alarm display information W2 different from the first alarm display information W1 (blinking display). For example, when the light notification unit 264 is a light-emitting element such as an LED, the LED is displayed as the second alarm display information W2 by turning on the LED instead of blinking (step S212: alarm observation state).

  At time t5 after time t4, the measured value V that has deviated from the set range Rth has fallen within the set range Rth (the measured value V that has exceeded the upper limit alarm threshold Vth1 has not exceeded the upper limit alarm threshold Vth1). . Even in this case, the light notification unit 264 continues to output the second alarm display information W2. That is, the light notification unit 264 is lit and displayed.

  At time t6 after time t5, the continuous time T2 during which the measured value V of “breathing” or “pulse” does not deviate from the set range Rth is equal to or longer than the second set time Tth2 as the second set time (T2). ≤ Tth2). In this case, since the alarm situation has not occurred (step S214-Yes), the light notification unit 264 stops the lighting display by stopping the output of the second alarm display information W2 (step S202: alarm monitoring). Status).

  At time t7 after time t6, the measured value V of “breathing” or “pulse” deviates from the set range Rth. For example, the measured value V exceeds the upper alarm threshold Vth1. Further, at time t8 after time t7, when the continuous time T3 during which the measured value V of “breathing” or “pulse” deviates from the set range Rth is equal to or longer than the first set time Tth1 (T3 ≧ Tth1) ), An alarm situation has occurred (step S204-Yes).

  At time t8, the sound notification unit 262 outputs the alarm sound AL. The light notification unit 264 blinks by outputting the first alarm display information W1 (step S206: alarm notification state). As described above, when the staff instructs to stop the alarm, the state shifts from the alarm notification state to the alarm response state.

  As described above, the notification device of the present invention uses the patient status display device 10 (FIGS. 1 and 2) of the patient status display system 1 (FIG. 1) to perform the above-described alarm processing (step S104 in FIG. 7, FIG. 9). , FIG. 10). In order to realize the alarm processing, the notification device (patient state display device 10) of the present invention is configured such that the measured value V (FIG. 10) is set to the set range Rth (FIG. 10) in the alarm monitoring state (step S202 in FIGS. 9 and 10). 10), and a continuous time T1 (FIG. 10) in which the measured value V deviates from the set range Rth is set to a first set time Tth1 (FIG. 10). ) Or more (steps S204-Yes in FIGS. 9 and 10), the sound notification unit 262 (FIGS. 3 and 10) that outputs the alarm sound AL (FIG. 10) And a light notification unit 264 (FIGS. 3 and 10) that outputs the first alarm display information W1 (FIG. 10). In the alarm notification state where the alarm sound AL and the first alarm display information W1 are output (step S206 in FIGS. 9 and 10), when the staff instructs to stop the alarm, the sound notification unit 262 outputs the alarm sound AL. To stop. After the operation for completing the alarm response, the light notification unit 264 outputs the second alarm display information W2 (FIG. 10) different from the first alarm display information W1.

  Further, the notification device (patient status display device 10) of the present invention uses the patient status display device 10 (FIGS. 1 and 2) of the patient status display system 1 (FIG. 1) to perform the above-described alarm processing (steps in FIG. 7). S104, FIGS. 9 and 10) are realized. In order to realize the alarm processing, the setting is performed in the alarm observation state (S210-No and S212 in FIGS. 9 and 10) in which the output of the first alarm display information W1 (FIG. 10) is continued after the operation for completing the alarm response. Even when the measured value V (FIG. 10) that has deviated from the range Rth (FIG. 10) falls within the set range Rth, the light notification unit 264 (FIGS. 3 and 10) outputs the second alarm display information W2. To continue.

  Further, the notification device (patient status display device 10) of the present invention uses the patient status display device 10 (FIGS. 1 and 2) of the patient status display system 1 (FIG. 1) to perform the above-described alarm processing (steps in FIG. 7). S104, FIGS. 9 and 10) are realized. In order to realize the alarm processing, in the alarm observation state (S212 in FIGS. 9 and 10), the continuous time T2 (FIG. 10) in which the measured value V (FIG. 10) does not deviate from the set range Rth (FIG. 10) is set. When it is longer than the second set time Tth2 (FIG. 10) (S214-Yes in FIGS. 9 and 10), the light notification unit 264 (FIGS. 3 and 10) stops outputting the second alarm display information W2. In the alarm monitoring state (S202 in FIGS. 9 and 10) after the output of the second alarm display information W2 is stopped, the control unit 100 (FIG. 3) monitors whether the measured value V is out of the set range Rth. I do.

  Further, the notification device (patient status display device 10) of the present invention uses the patient status display device 10 (FIGS. 1 and 2) of the patient status display system 1 (FIG. 1) to perform the above-described alarm processing (steps in FIG. 7). S104, FIGS. 9 and 10) are realized. In order to realize the alarm processing, the alarm observation state (FIG. 9 and FIG. 9) is performed even after the third set time longer than the second set time Tth2 (FIG. 10) has elapsed after the alarm handling completion operation. If the state has not shifted from the alarm monitoring state (S202 in FIGS. 9 and 10) from S212 in FIG. 10, the sound notification unit 262 (FIGS. 3 and 10) outputs the alarm sound AL (FIG. 10), and the light notification unit 264. (FIGS. 3 and 10) output the first alarm display information W1 (FIG. 10).
